ALBERT WILLARD CASE, OF HIGHLAND PARK, CONNECTICUT.

PAPER-FINISHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 776,887, dated December 6, 1904.

Application filed December 17, 1903. $611M (N0 model) To all whom it may concern.-

Be it known that I, ALBERT WILLARD Case, a citizen of the United States, and a resident of Highland Park, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Paper-Finishing Machines, of which the following is a specification.

The invention relates, generally speaking, to a machine for finishing paperthat is, to provide a higher finish than is produced in the ordinary method of manufacturing paper and while belonging to the general class of paper-finishing machines it should perhaps be more properly called a glassing-machine.

The object of the invention is to provide such a machine through which a web or strip of paper may be passed and will be acted upon as to its surface by a glassing-flint as it is passed through the machine, thus securing an unusually high finish for the surface of the paper.

A still further object is to provide a mechanism for operating a glassing-flint that will always hold said flint in perfect and true alinement with reference to the surface of the paper acted upon.

A still further object is to provide an adjustable bed or platen which may easily be moved into position to bring the glaSSing-flint into operative position with reference to the paper and vary the amount of pressure exerted by said flint without in any way changing the position of the flint or its alinement in action.

Another object of the invention is to pro 'vide a platen-bed which is adjustable with reference to the glassing-flint and provides a means for securing therein interchangeable platens of various sizes and material and at the same time to vary the length of stroke of the glassing-flint when the machine is used with platens of different sizes.

Referring to the drawings, Figure 1. is a View in end elevation of the machine, showing the method of passing the paper through it. Fig. 2 is a detail side view of the parts of the glassing-maehine shown in Fig. 1. Fig. 3 is a plan view of the parts shown in Fig. 2,

the platen-bed and platen being removed. Fig. 4 is a detail plan View of the platen and platen-bed seen as indicated from the sectionlines 1 1 of Fig. 2. Fig. 5 is a detail sectional view on the line 5 5 of Fig. 2 looking in the direction indicated by the arrow. Fig. 6 is a similar view in cross-section on the line 6 6 of Fig. 2..

In the accompanying drawings the numeral 1 denotes a bed-plate properly secured upon the base 2 and having end frames 3 1. At one end of the bed-plate is arranged a journalframe 5, in bearings 6 of which is mounted the main shaftZ. This is a divided shaft and terminates at its adjacent ends in disks 8 9, between which is secured a crank-pin 10. The plates each have a radial slot 11, along which this crank-pin may be adjusted and secured at any desired radial distance from the center of the shaft and disks. Outside of the frame and upon one of the shaft-sections is a fly-wheel 12, which aids in securing a uniform and steady rotation of the parts. The shaft is driven through any suitable means. as by belt in connection with a pulley 13, which is preferably of the friction type and has an operating-handle 14. for causing it to drive or release the main shaft.

A connecting-rod l5, suitably journaled on the crank-pin, extends to a cross-head 16, which is of peculiar construction. This crosshead is made up in sections and has at each side and substantially in the plane of the axis of the main shaft 7 a pair of sliding bearings 17 18 of cylindrical form, which inclose and Those bars 19 20 are secured at either end in the frames 3 and a, and a third guide-bar, 21, is arranged above the bars 19 20 and in a plane substantially midway thereof. A third sliding hearing 22, arranged at the top of the cross-head 16, forms an auxiliary guide for said crosshead. It will be observed that the arrangement of the bars or slideways is substantially triangular with the base of the triangle lying in a plane parallel with the base of the machine 1. This triangular arrangement gives a very rigid construction and provides a crosshead slide which will be maintained in absolute alinement at all times. At the bottom of the cross-head and suitably secured therein is a glassing-fiint 23, which may be of any desired form, although a cylindrical flint is preferably used.

Adjustably arranged upon the bed 1 and within range of the glassing-flint is a platenbed 24, which is preferably grooved, as at 25, to receive a platen 26, the latter being secured within the groove in any desired manner and having its opposite ends rounded or beveled, as at 27. In practice this platen 26 rests upon a thin web of resilient material placed between it and the platen-bed 24. The bed is bored at a number of places, as shown herein, at each end, and within these bores rest the eccentric portions 28 of shafts 29, which at their outer ends terminate in worm-wheels 30 31. These worm-wheels engage worms 32 33, carried upon a shaft 34, and the latter is provided at its extremity with a hand-wheel 35, by which the worms may be turned and through the movement of the worm-wheels and connected shafts will raise and lower the platenbed and its contained platen.

At either side of the bed 2 are arranged frames 36 37 which support the paper to be finished as well as the feed mechanism for drawing said paper across the platen. At either side of the bed are guide-rolls 38 39, and the paper to be glassed is fed from a reel 40 across these rolls and the platen which lies intermediate thereof and about a roll 41. From the roll 41 the paper passes through a pair of feed-rolls 42, provided with a means, as 43, for tensioning the rolls with reference to each other, and from this point the web of paper passes to a reel 44.

In the operation of the device the web of paper is fed slowly across the platen, and the cross-head, with its glassing-fiint, is reciprocated rapidly along the upper surfaceof the paper, pressing it down upon the platen, and thus giving it a very high finish. It will be observed that the cross-head and flint never change position with reference to the bed, but that the desired pressure is secured by raising the platen-bed and platen.

The feed-rolls 42 and the reels are driven in any suitable manner, and of course it is understood that the speed of the paper through the machine as well as the speed of the main shaft 6 and consequent reciprocations of the cross-head may be varied at will to suit the exigencies in any particular case. Thus a greater or less degree of gloss or finish may be produced for various sorts of paper.

Of course it is perfectly obvious that in lieu of feeding a web or strip of paper transversely of the platen and glassingflint individual sheets of paper might be subjected to treatment with equal facility. These sheets of course would be fed over the platen and subjected to the action of the glassing-flint in any desired manner and by any desired mechanism for accomplishing the result automatically or may be passed through the machine by an operator.
